Calibrachoa plant named ‘USCAL84704’

ABSTRACT

A new and distinct cultivar of  Calibrachoa  plant named ‘USCAL84704’, characterized by its compact, outwardly spreading and mounding plant habit; freely branching growth habit; dense and bushy appearance; early and freely flowering habit; dark violet-colored flowers with dark purple-colored centers and yellow-colored throats; and good garden performance.

Botanical designation: Calibrachoa sp.

Cultivar denomination: ‘USCAL84704’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Calibrachoa plant, botanically known as Calibrachoa sp. and hereinafter referred to by the name ‘USCAL84704’.

The new Calibrachoa plant is a product of a planned breeding program conducted by the Inventor in Higashiomi, Shiga, Japan and Bonsall, Calif. The objective of the breeding program is to create new Calibrachoa plants with uniform plant habit, freely branching growth habit, unique flower coloration and good garden performance.

The new Calibrachoa plant originated from a cross-pollination made by the Inventor on May 9, 2008 in Higashiomi, Shiga, Japan of a proprietary seedling selection of Calibrachoa sp. identified as code name CJ08-76, not patented, as the female, or seed, parent with a proprietary seedling selection of Calibrachoa sp. identified as code name CJ08-32, not patented, as the male, or pollen, parent. The new Calibrachoa plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in Bonsall, Calif. on May 27, 2009.

Asexual reproduction of the new Calibrachoa plant by terminal cuttings in a controlled environment in Bonsall, Calif. since May 28, 2009 has shown that the unique features of this new Calibrachoa plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Calibrachoa have not been observed under all possible environmental conditions and various cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘USCAL84704’. These characteristics in combination distinguish ‘USCAL84704’ as a new and distinct Calibrachoa plant:

-   -   1. Compact, outwardly spreading and mounding plant habit.     -   2. Freely branching growth habit; dense and bushy appearance.     -   3. Early and freely flowering habit.     -   4. Dark violet-colored flowers with dark purple-colored centers         and yellow-colored throats.     -   5. Good garden performance.

The new Calibrachoa plant can be compared to plants of the female parent selection. Plants of the new Calibrachoa differ primarily from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Calibrachoa are more mounding than plants         of the female parent selection.     -   2. Plants of the new Calibrachoa are more freely branching than         plants of the female parent selection.     -   3. Plants of the new Calibrachoa and the female parent selection         differ in flower color as plants of the female parent selection         have solid dark violet-colored flowers.

The new Calibrachoa plant can be compared to plants of the male parent selection. Plants of the new Calibrachoa differ primarily from plants of the male parent selection primarily in flower color as plants of the male parent selection have purple-colored flowers with dark violet-colored centers. In addition, plants of the new Calibrachoa are more mounding than plants of the male parent selection.

Plants of the new Calibrachoa can be compared to plants of the Calibrachoa ‘USCALI99’, disclosed in U.S. Plant Pat. No. 17,679. In side-by-side comparisons conducted in Bonsall, Calif., plants of the new Calibrachoa differed primarily from plants of ‘USCALI99’ in the following characteristics:

-   -   1. Plants of the new Calibrachoa were more mounding than plants         of ‘USCALI99’.     -   2. Plants of the new Calibrachoa and ‘USCALI99’ differed in         flower color as plants of ‘USCALI99’ had purple-colored flowers         with dark purple-colored venation.

Plants of the new Calibrachoa can be compared to plants of the Calibrachoa ‘Imperial Purple’, not patented. In side-by-side comparisons conducted in Bonsall, Calif., plants of the new Calibrachoa differed primarily from plants of ‘Imperial Purple’ in the following characteristics:

-   -   1. Plants of the new Calibrachoa were more mounding than plants         of ‘Imperial Purple’.     -   2. Plants of the new Calibrachoa and ‘Imperial Purple’ differed         in flower color as plants of ‘Imperial Purple’ had solid dark         violet-colored flowers.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the late spring and early summer in 15-cm containers in a polyethylene-covered greenhouse in Bonsall, Calif. During the production of the plants, day temperatures averaged 24° C., night temperatures averaged 18° C. and light levels averaged 7,000 foot-candles. Plants were pinched one time and were seven weeks old when the photographs and description were taken.
